Hi,

We have released 1.1 version of CloudBase on sourceforge-
http://cloudbase.sourceforge.net/

[ CloudBase is a data warehouse system built on top of Hadoop's Map-Reduce
architecture. It uses ANSI SQL as its query language and comes with a JDBC
driver. It is developed by Business.com and is released to open source
community under GNU GPL license]

Please give it a try and send us your feedback on CloudBase users group-
http://groups.google.com/group/cloudbase-users

Thanks,
Tarandeep
